The incident, which took place late Friday night around the Bwari Area Council of Abuja, left three soldiers wounded and eight personnel killed.
Two of the slain personnel were officers, including a captain and lieutenant, while the remaining were soldiers.
According to a source within the army, the main aim of the terrorists is to attack the Nigerian Law School in Bwari and they may have already camped in the area.
The Nigerian army has yet to officially react to the attack. Army spokesperson Onyema Nwachukwu did not pick up or return calls to his phone. But different intelligence sources had told PREMIUM TIMES that the government was aware of plans by terrorists to attack some places in the capital and security had been increased around the city.
On Monday, the government officially shut the Federal Government College, Kwali, in the Kwali Area Council of Abuja after terrorists attacked a community near the school.
